I will say that the HiFiMan IEM's are really good. I had a pair of the RE-262's and they are fantastic. I ended up returning them though after I got my Ety's cause the Re-262 can't hold a candle to the Etymotics. But, for the money, they are fantastic, but a bit out of your budget at $150...and they are not bass heavy...very mid forward which I personally love. The RE-0 may be better in that regard, I haven't listened to them, but in general, the HiFiMan stuff is good.
For great bass on the cheap I still stand by my suggestion for the GR02 Bass. In fact, I am listening to some 311 through them now and the bass is deep and there's lots of it. I don't have much time on these yet so I suspect they may even improve with some time. Definitely worth the $36 I spent on them.
For closed over the ear, I can't really back it with anything but reviews, but you might look at the Equation Audio RP-15MC
or the Panasonic RP-HTF600-S
, or even the Sony MDR-XB500
which are supposed to be bass monsters. The Sony MDR-XB700
is even better though they range up around $80. You may need to stretch the budget to $50ish, but certainly any of these can be found for less than $60, likely at $50 or even less except the last Sony if you shop around. The Sony's would be my top choice.
Or if you really want to sssstttttttrrrrrrrreeeeeeettttttccccccccchhhhhhhhh hhhhhh that budget, the Denon D2000
are a hifi bass lover's dream.
Heck, I might even grab a pair of the Sony XB500 for shts and giggles. I need a super bassy headphone since I sold my Beyerdynamics...which are another great choice, but also another pricey one that needs an amp.
